When I wrote this code, I did not attempt to #ifdef it for different systems.
I left that up to the user, who probably knows more about those systems than
I, or at least can take the time to find out.

I did, however, attempt to make porting very easy.  I used the standard I/O
package wherever possible, such as reading/writing score files and
saved games.  A few things however, had to be system dependent:

1.)  In init.c, the routine edchars().  This routine contains various
     system-dependent ioctl calls.  These are intended to disassociate
     any special meaning from keyboard characters.  The program is run
     in cbreak mode instead of raw so that keyboard signals can be recieved.
     However, no other special treatment of the characters by the terminal
     device driver is desired.
     The simplest solution to this is to just delete, or comment-out, the
     contents of the routine edchars().  You may find that a few keyboard
     characters, like ^J, don't work.  But you should be able to play
     just fine with this minor inconvenience.  This routine should work
     find on BSD systems.

2.)  In save.c, to check the validity of saved game files, stat() and
     gettimeofday() are called.
     This should be OK for most UNIX systems, but non-UNIX
     systems probably won't like it.  Some equivalent routine should
     be subsituted, or this functionality deleted.  If you want to delete
     these, you will have to delete the references to associated structures
     like:

    struct stat sbuf;
    struct timeval tv;
    struct timezone tzp;

    Then you must make sure that these structures, or fields within, are
    not written/read to/from the save file, or referenced in any way.
    This should be fairly easy.

3.)  In message.c, in the routine rgetchar(), there is a switch statement
     with a call to tstp() in it.  This is BSD-dependent.  Non-BSD users
     can remove the the case containg the tstp() call from the switch
	 statement.
